Les Hauts de Castelroc

Climbing the slopes of Mont Rouvière, we find ourselves at Les Hauts de Castelroc. This remarkable residential complex, designed by architect Claude Gros, stands as a testament to innovative urban planning and architectural vision. Les Hauts de Castelroc isn’t just a place to live. It’s a statement, a bold experiment in blending urban density with the natural beauty of its hillside setting. Built in 1973, Les Hauts de Castelroc was part of a larger plan to develop the Hauts de Saint-Tronc area. Architect Xavier Arsène-Henry commissioned Claude Gros to create a master plan for this hilly terrain, which was owned by the Savoisienne company. The city’s urban plans, recognizing the scenic value of the hills, called for dense construction at the base to preserve the natural landscape higher up. This approach allowed Les Hauts de Castelroc to embrace the surrounding hillside, incorporating the existing pine forest into the design. The complex comprises four main buildings, rising 12 to 15 stories high. They seem to climb the slopes, their staggered arrangement creating a dynamic visual interplay. Gros’s design moves away from the traditional concept of a uniform building, instead opting for a more fluid, interconnected structure. Three distinct housing blocks cluster around a central core. This core houses the vertical circulation systems, with a network of airy walkways connecting the different sections. The interplay of heights and setbacks creates a sense of openness, allowing light to penetrate deep into the structure. The varying levels integrate the building into the slope, while the terraced setbacks around the central void create a wider opening at the top. This allows for breathtaking views of the city below. Glass-walled elevators add a cinematic touch, offering a moving panorama as residents ascend to their apartments. The exterior facades of the buildings are striking. Prefabricated panels, adorned with a brown glass paste motif, create a textured surface. Balconies with transparent railings, interspersed with vertical wooden screens, further enhance the visual appeal while also providing privacy. Les Hauts de Castelroc is more than just a building. It is an experience. It’s a place where architecture and nature intertwine, offering residents both the convenience of city living and the tranquility of a hillside retreat. As you wander through the complex, you’ll discover a network of paths and walkways that invite you to explore the surrounding landscape. The proximity of the hill allows for long walks, turning the residence into a gateway to a public park. And from the balconies, panoramic views of Marseille unfold, a constant reminder of the city’s vibrant energy.
